Description
Prevost Industrial Profile Male NPT Plug - ISO 6150 B
Prevost IRP Industrial Profile Male NPT Plugs provide the mating plug connection for compatible Prevost ISI compressed-air couplers using the Industrial / ISO 6150 B profile. This listing combines the IRP 06, IRP 08, and IRP 11 plug families with multiple male NPT thread sizes, allowing the quick-connect profile and threaded equipment connection to be selected independently.
Prevost manufactures its compressed-air plugs from nitrided steel for resistance to scratches, corrosion, vibration, and repeated connection cycles. Precise standardized dimensions and tolerances help the plug interface correctly with a compatible coupling and seal, supporting a dependable compressed-air connection while helping reduce leakage at frequently used quick-connect points.

Understanding Plug Profile vs. Male NPT Size
The Industrial plug profile and male NPT thread size describe two different parts of the adaptor and should not be treated as the same measurement.
The IRP profile determines which quick coupler accepts the plug. The male NPT connection determines which female-threaded pneumatic tool, fitting, hose assembly, manifold, regulator, or machine connection the plug screws into.
- IRP 06: 1/4" Industrial profile family
- IRP 08: 3/8" Industrial profile family
- IRP 11: 1/2" Industrial profile family
- Male NPT thread size is independent of the quick-connect plug profile.
- Always verify both the plug profile and threaded equipment connection before ordering.

Why Plug Quality Matters
Accurate Dimensions
A compressed-air plug must conform closely to the dimensions and tolerances of its specified connection profile. Correct geometry allows the plug to seat properly inside the coupling and interface correctly with the seal.
Reliable Sealing
The plug and coupling work together to create the compressed-air connection. Correctly matched Prevost plugs and couplers help maintain a dependable seal at this frequently connected and disconnected point in the air system.
Durable Construction
Prevost uses nitrided steel for its plugs to provide resistance to scratches and corrosion, helping the connection surface withstand repeated professional use.
Industrial / ISO 6150 B Compatibility
These plugs use the Industrial / ISO 6150 B connection profile. The selected IRP family should match the corresponding Industrial coupler family.
- IRP 06 plugs pair with compatible ISI 06 Industrial couplers.
- IRP 08 plugs pair with compatible ISI 08 Industrial couplers.
- IRP 11 plugs pair with compatible 1/2" Industrial coupler families.
- Male NPT thread size does not determine quick-coupler compatibility.
- Two plugs with the same male NPT thread may use different quick-connect profiles.
- Verify the existing coupler profile before selecting a plug.
Male NPT Connection Options
1/4" Male NPT
Available with the IRP 06 and IRP 08 Industrial plug families for equipment or fittings using a 1/4" female NPT connection.
3/8" Male NPT
Available across the IRP 06, IRP 08, and IRP 11 families, providing Industrial-profile options for equipment with a 3/8" female NPT connection.
1/2" & 3/4" Male NPT
1/2" male NPT is available with the IRP 08 and IRP 11 families. The IRP 11 family also includes a 3/4" male NPT option for larger threaded compressed-air connections.

Installation & Safety Guidance
- Depressurize pneumatic equipment before installing, removing, or replacing compressed-air fittings.
- Confirm both the Industrial plug profile and male NPT connection size before installation.
- Use thread-sealing materials and installation practices suitable for compressed-air NPT connections.
- Do not force a plug into a coupler from a different profile family.
- Inspect plugs periodically for excessive wear, corrosion, deformation, or damaged connection surfaces.
- Replace damaged or excessively worn plugs to maintain dependable coupling performance.
- Do not exceed the pressure, temperature, or service ratings of the coupler, hose, tool, or other connected equipment.
- Compressed-air components should be installed and serviced by qualified personnel.

Frequently Asked Questions
Are these plugs or couplers?
These are Prevost IRP plugs, also described as ISO B adaptors. The plug inserts into a compatible Industrial-profile quick coupler.
What connection profile do these plugs use?
These plugs use the Industrial / ISO 6150 B compressed-air connection profile.
What is the difference between the IRP profile and male NPT size?
The IRP profile determines which quick coupler accepts the plug. The male NPT dimension determines which female-threaded pneumatic component the plug screws into. They are separate specifications.
Which plug family fits an ISI 06 coupler?
Use the corresponding IRP 06 Industrial plug family with a compatible ISI 06 Industrial coupler.
Which plug family fits an ISI 08 coupler?
Use the corresponding IRP 08 Industrial plug family with a compatible ISI 08 Industrial coupler.
Which plug family is used for the 1/2" Industrial profile?
The IRP 11 family is the corresponding Prevost plug family for compatible 1/2" Industrial-profile couplers.
What are Prevost plugs made from?
Prevost specifies nitrided steel construction for its compressed-air plugs.
Why does Prevost use nitrided steel?
Prevost identifies its nitrided-steel plugs as scratch and corrosion resistant, helping the plug maintain its connection surface through repeated use.
Why are plug dimensions and tolerances important?
A correctly manufactured plug must match the dimensions and tolerances of its connection profile so it seats correctly in the coupling and interfaces properly with the coupling seal.
Does male NPT thread size determine quick-coupler compatibility?
No. Male NPT size determines the threaded equipment connection. Quick-coupler compatibility is determined by the IRP Industrial plug profile.
Can the same NPT thread size be available on different IRP profiles?
Yes. For example, 3/8" male NPT is available on IRP 06, IRP 08, and IRP 11 variants. The correct plug profile must still be selected to match the coupler.
Can these plugs be installed directly into pneumatic tools?
Yes, when the tool has the matching female NPT connection and the shop's quick coupler uses the corresponding Industrial profile.
Why use a matching Prevost plug with a Prevost coupler?
Prevost manufactures its plugs to standardized dimensions and tolerances so they properly interface with compatible couplings and their sealing components.
